The P220A automobile fault code indicates a problem with the NOx sensor or its circuit. The most common symptom is the illumination of the engine light or service engine soon warning light.
The cause of this fault code could be a faulty NOx sensor, an open or shorted NOx sensor harness, a poor electrical connection in the NOx sensor circuit, or a faulty Engine Control Module (ECM).
The importance of repairing this issue lies in the fact that it can lead to increased emissions and decreased fuel efficiency. The repair difficulty is moderate, with a repair time of 1.0 hour. To fix this issue, one should visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.

P220A: Your Car’s Oxygen Sensor Needs Attention
The P220A fault code is related to the NOx Sensor circuit malfunction.
This code is commonly found in lean burn and direct injection vehicles that use a Selective Catalytic Reduction System (SCR). The NOx sensor detects when a regeneration is required and when it is complete. A heater circuit is necessary to quickly get the NOx sensor up to operating temperature for reliable performance.
The NOx sensor has a module located near it that communicates with the engine control module.
The P220A code specifically refers to the NOx Sensor Supply Voltage Circuit for Bank 1 Sensor 1.
FAQ
If you see the engine light on or service engine soon warning light, it could be due to the P220A fault code. This code is usually caused by a faulty NOx sensor, an open or shorted NOx sensor harness, poor electrical connection in the NOx sensor circuit, or a faulty Engine Control Module (ECM). To fix this issue, you should visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.
If you’re experiencing the P220A fault code, which is indicated by the engine light or service engine soon warning light being on, there are a few things you can do to fix it.
